The 25-year-old left-hander scored 19 runs before being run out in Sri Lanka's opening match of this edition against Canada. As he prepares to face Pakistan in a Group A match on Saturday, Tharanga said he will now be looking to make a better start and to score big.
"As a batsman, my plan is if I get a good start to always capitalize on it a get a good score," Tharanga told reporters.
"One of my plans is to get a hundred in a big game like a World Cup (game)."
Tharanga has scored three half-centuries in World Cup matches since his debut in 2007, with a top score of 73 against New Zealand in the semifinals in the Caribbean.
Tharanga made it clear he was not underestimating Saturday's opponent, which beat New Zealand 3-2 in a one-day series which finished there earlier this month.
"They (Pakistan) are a very good side, a very good bowling attack. They did well in New Zealand and we are looking forward to the game."
But he added: "It's really good playing in home conditions with the home support."
